Problem with variables InternalReadOnly and SelfUpdating

[Mauri]

I am creating a custom component and looked UniGUI other components to see the methods used to manipulate data for example TUniCustomDBComboBox, TUniCustomDBMemo! In all they have an assignment for InternalReadOnly variable (InternalReadOnly: = not AllowEdit) and also compared the variable 'SelfUpdating', but realized that this variable is in UniGUIClasses class. I have put this class in the uses clause and when compiling is showing the following messages:

 

Undeclared identifier: 'InternalReadOnly'

Undeclared identifier: 'SelfUpdating'

 

What could be wrong?

 

Examples where it is being using:

 

 

unit ISComponet;

interface

uses Classes, Vcl.Graphics, DesignIntf, Controls, DBCtrls, DB,
     UniPanel, UniGUIClasses, UniGUIInterfaces, uniGUICoreInterfaces,
     UniGUITypes, UniDBUtils;

type

  TISComb = class(TISBase, IUniDBControl)
  private
    ...
    procedure ActiveChange(Sender: TObject);
    ...
  protected
    procedure DataChange(Sender: TObject); virtual;
    ...   
  public
    ...
  published
    ...
  end;

procedure Register;

implementation

procedure TISComb.ActiveChange(Sender: TObject);
begin
  if (not IsDesigning) and (not IsDestroying) then
    InternalReadOnly:= not AllowEdit;  // Here give problem compiling
end; 

procedure TISComb.DataChange(Sender: TObject);
begin
  if SelfUpdating then // Here give problem compiling
    Exit;
  ...
end;

...

The TISBase class is inherited from TUniPanel class. My new component inherits all the properties of a Panel (TUniPanel) and adds the data connection to display the Caption.

Any ideas about the problem?

You need to derive it from TuniFormControl

TUniPanel doesn not provide those methods

Hi Farshad,

 

Thanks for the reply, I will change the inheritance of my component!
